Serial No. 608,892.

This invention relates to new and useful improvements in wall flashingsvand has particular relation to through wall flashings such as are usedin brick or other masonry Walls to prevent water soaking th-rough andrunning down the inside of the wall.

An object of the invention is to provide a through wall flashing whichmay be manufactured at low cost and which when em-y tion with theaccompanying drawing wherein the invention is shown. It is to beunderstood that the invention is not limited to the details disclosedbut includes all such variations and modifications as fall within thespirit of the invention and the scope of the ap ended claims.

Fig. 8 is a detail sectional viewon an enlarged scale, the view beingtaken along the line 8-8 of Fig. 7.

The improved flashing of the present invention is made up in sections orlengths and of sheet metal, preferabl copper. In the drawing theflashing of ig. 1 -is of a width for use in connection with 8 inchwalls, while the flashing of'Fig. 2 is of a. somewhat greater Width andis adapted for use in 12 inch walls. However, the invention is the saineas applied to either flashing, the only difference in the flashingsresiding in'their width.

The flashing comprises a body or strip 10 which may be of a convenientlength and the desired width and adjacent onelongitudinal edge thematerial of the body is offset upwardlyfrom the plane of the body asyindicated aty 9 to form a led e 11 and the extreme edge portion of sailongitudinal edge of the body is then inclined-upwardly providing avflange 12 forming a water stop. Extending in adirection generalltransversely of the body and running rom the ledge 11 substantially tothe opposite edge of the body area series of hollow zig-zag ribs. 13.

Ribs 13 are generally wedge or inverted V-shape in transverse crosssection as clearly shown in Figs. 3, 5, 6 and 8 and these ribsmay bepressedA or rolled into the bod 10 and are open at their undersidesprovi ing zig-zag grooves at 14. A comparison of Figs of the latterfigure are of a length greater than the length of the corresponding ribsof Fig. 1, this increase in length of the ribs equal to the increaseinof that figure as com.

in Fig. 2 being width of the -bod pared with the Fig. 1.

Reference character 15 generally indiody of the flashing of 1 and 2 willshow that the 'ribs 13 cates a portion of a brick wallA made up' ofbricks 16 and horizontal and vertical layers 17 and 18 respectively ofmortar. ObviouslIy, the mortar binds j the bricks together.

n the drawing, 19 indicates the inner sur# face of the wall, while 20indicates 'the outer surfaceV thereof, and referring now particu- -larlyto Fig. 5 it will be noted that thev imyply to each figure. edge of theflashing 10 of Figs. 6 and 7 exproved flashing 10 is embedded in ahorizontal layer 17 of mortar with its outer edge 10a: substantiallyflush with the outer surface 20 of the wall and with its flange 12disposed inwardly of the inner surface of the wall. Also, it will benoted that the mortar fills the zig-zag grooves 14 and completelyencloses the zig-zag ribs 13 whereby the body 10 or flashing 10 issubstantially completely embedded in the mortar.

Attention is also directed to the fact that the ledge 11 is as high orslightly higher in the wall than the tops of the ribs 13, and that theflange 12 extends above the ledge. Should water seep down through themortar connecting the bricks or should water attempt to run down theinner surface 19 of the wall it will be caught by the flashing 10 or bythe flange 12 of'said flashing and directed or diverted to the outersurface of the wall. There are no obstructions of any kind between theribs 13, and the spaces between them f'orm channels, and it willtherefore be apparent that water caught by the flange 12 or interceptedby the body of the flashing will be carried outwardly between the ribs.

Moreover, the sections of the wall above and below the flashing will beheld against lateral movement in all directions since in order that oneportion of the wall move laterally with respect to the other it will benecessary to shear off the mortar or cement entering the grooves 14 aswell as that between the ribs 13 of the flashing. Should one portion ofthe wall attempt to move laterally with respect to another portionthereof in the direction of the length of the wall obviously the ribs 13and the mortar in the grooves 14 will prevent such movement. Should thetendency for relative movement between sections of the wall be in eitherdirection transversely of the wall it is obvious that the mortarreceived in the bends in the ribs together with the connection betweenthe main body of the mortar and the mortar in the grooves 14 vwillprevent such movement.

Referring now particularly to Figs. 6 and 7 the arrangement of theflashin in the wall is the same as that already escribed and thereference characters used above ap- However, the outer tends beyond theouter surface 20 of` the wall and after the mortar has set, thisextending edge portion 21 is bent downwardly as shown in Fig. 6 and mayform a flashing over-lying the upperedge of an upstanding portion 22 ofa roof flashing. In place of the relatively wide portion'21 the body orflashing 10 may extend but slightly beyond the outer surface of the wallso that when it is bent downwardly after the mortar sets it forms arelatively narrow drip edge.

In addition to forming a tie to prevent relatively lateral movementbetween the sections of the wall the ribs and grooves 13 and 14 alsoprovide means whereby succeeding sections of the flashing used along thelength of a wall may be interlocked; The manner of interlocking theadjacent ends of succeeding sections is illustrated in Figs. 7 and 8 andthere it will be noted that the end of one section is disposed over theend portion of the next adjacent section and that the end groove in thelower side of the upper section receives the end rib of the lowersection. This connection locks the sections together since it securesthem against relative lateral movement in any direction owing to thefact that the grooves and ribs zig-zag. As the over-lapping end portionsof Athe sections are embedded in the mortar or cement and as the weightof the upper portion of the wall will be on the flashing it will beapparent that the over-lapping end portions of succeeding sections ofthe flashing will be held against relative vertical movement.

From the foregoing description it will be apparent that I have provideda through wall flashing which may be manufactured at low cost since thegrooves and ribs may be easily pressed or rolled into the sheet stock.Further, it will be apparent that in use my improved flashing willeffectively tie together the upper and lower sections of a wall toprevent relative lateral movement between such sections. Also,succeeding sections of the flashing used along the length of a wall maybe easily interlocked and without .the use of solder or the like sinceit is but necessary to dispose the end portion of one section over orunder the end portion of the next adjacent section to have the endgroove of one section receive the end zig-zag rib of the other section.
